A linear response framework for simulating bosonic and fermionic correlation functions illustrated on quantum computers
Efekan Kökcü, Heba A. Labib, J. K. Freericks +1
Response functions are a fundamental aspect of physics; they represent the link between experimental observations and the underlying quantum many-body state. However, this link is…
Subspace Diagonalization on Quantum Computers using Eigenvector Continuation
Akhil Francis, Anjali A. Agrawal, Jack H. Howard +2
Quantum subspace diagonalization (QSD) methods are quantum-classical hybrid methods, commonly used to find ground and excited state energies by projecting the Hamiltonian to a smal…
An entanglement-based volumetric benchmark for near-term quantum hardware
Kathleen E. Hamilton, Nouamane Laanait, Akhil Francis +8
We introduce a volumetric benchmark for near-term quantum platforms based on the generation and verification of genuine entanglement across n-qubits using graph states and direct s…
Robust measurements of -point correlation functions of driven-dissipative quantum systems on a digital quantum computer
Lorenzo Del Re, Brian Rost, Michael Foss-Feig +2
We propose and demonstrate a unified hierarchical method to measure -point correlation functions that can be applied to driven, dissipative, or otherwise open or non-equilibrium…
Measuring NISQ Gate-Based Qubit Stability Using a 1+1 Field Theory and Cycle Benchmarking
Kubra Yeter-Aydeniz, Zachary Parks, Aadithya Nair +5
Some of the most problematic issues that limit the implementation of applications on Noisy Intermediate Scale Quantum (NISQ) machines are the adverse impacts of both incoherent and…
Mapping the metal-insulator phase diagram by algebraically fast-forwarding dynamics on a cloud quantum computer
Thomas Steckmann, Trevor Keen, Efekan Kökcü +3
Dynamical mean-field theory (DMFT) maps the local Green's function of the Hubbard model to that of the Anderson impurity model and thus gives an approximate solution of the Hubbard…
